BRAKE FOR-RAILWAY-CARS.

Specification of Letters Patent'.

.Patented Apr. 15, 1919.

To all 'whom-Muay concern.'

, Be it known that I, JOHN VF. OCoNNoR, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois,haveinvented a certain'new and useful Improvement in Brakes for Railway-Gars, of which the following is a full, clear, concise, and exactdescription, reference being had to the yaccompanying drawings,

10 forming a part vof this specification. t

My invention relates to improvements in' brakes for railway cars. l Theobject of my invention is to provide a simple and eicient brake. f Y Inthe drawings forming a part of this specification, Figure 1- is an endelevation of a brake embodying my invention; Fig. 2 is a transversesection taken on line 2-2 of Fig. 3; Fig. 3 is a vertical longitudinal20 section taken on line 3-3` of Fig. 1; Fig. 4

is a horizontal longitudinal section taken on line 1 -1 of Fig. 1; Fig.5 is a cross sectiontaken on line 5-5 of Fig. 3; Fig. 6 is an enlar eddetail of the operating pawl; and is an enlarged detail of the hanger towhlch the upper end of the handle is attached. Y y

Referring to the drawings, the numeral 6 indicates a partrof Va railroadcar, as, for I instance, the end thereof, to which the brake is adaptedto be secured. A casing 7 `adapted to contain parts hereinafterdescribedV is provided vat its inner end with the lugs 8, suitablyperforated as at 9 forfthe passage of suitablev means such as the rivets10 to secure the said casin to a railroad car. At its outer end thecaslng is provided with a closing member as, for instance, the plate 11,into the end of which the head 12 of a bolt 131s countersunk, the saidbolt passing through the member 6 of the car and being provided at itsinner end with the nut 14. Said bolt 13 serves as an axle for the drum15, the said druml being provided near its 4ends with the journals16`16and beinghollow intermediate said journals as indicated at 17. Thesaid drum bears a ratchet 19 provided with the teeth 20-20. It is alsoprovided with a pair of spaced-apart collars 21-21 forming an anchorageforthe brake chain 22. The ratchet 19, the collars 21 and the portions23-23 of the drum upon which the brake chainV is adapted to be wound areall made integral to give strength to the parts to prevent wear, and thesaid drum 'is hollowed out, as hereinbefore described,

and given a journalin near each end upon,` the axle member 1n or er toprevent binding of the drum upon the axlelin the event that through thevchain unusual torsion should be applied to said drum in braking. Thesaid casing is provided near its outer end and along its under surfacewith an opening 24:l through which the upper end 25 of the operatinghandle 26 is adapted to'pass. The 65 said handle -is provided withanintegral, wide pawl 27 which is adapted to be .thrown into engagementwithy the teeth 20 ofv theyk ratchet 19, the said handle being suspendedin its position b y means of the hanger 28, which 1s of semilunar shape,pivotally con-V nected with the handle by the wide pawl as at 29 at itslower end and extending over the ratchet at its upper end as at 30.LAThe said hanger is provided at eitheredgepwith the reinforcing.flar'ige31- and is adapted v in the operation of the parts to-ride upon theratchet itself. A holding `pawl 32 is pivoted within the casing by meansof a' hollow lug 33 inwardly extended from the 80 plate 11, said pawlhaving a handle 35. Thev1 said hollow lug 33 is most clearly-shown inFig. 2 of the drawings. One of the'collars 21-21 upon vthe drumisimmediately adjacent thevratchet, and at one point, as, for instance,indicated at the vnumeral 36 in Fig.

3 of the drawings, the drum is provided Vwith a slot which opens intothe lhollow` portion 17 thereof. Extending into said hollow portion andupon the interior ofthe drum there is provided a lip 38. The'purpose ofthis structure is to permit the insertion through the-'opening'36 of theend link 37 of the chain 22 and the passage of said link over thev saidlip, whereupon the bolt 9.5 13 is passed through the drum and the spacebetween the bolt 13 and the'nearest portion of the lip 38 issufficiently narrow, as indi-` cated at thenumeral 39 in Fig. 3 ofthedrawings, to prevent the withdrawal of the end link of the chain whenthe bolt 13 is in its position within the drum. By this means the brakechain is securely fastened .to the drum and the alternate links uponthe" end of thechain are received in the space40 be- 105 tween thecollars 21 upon said drum, and the intervening links lie flat upon theedges of said collar on 'the first wlndingof they chain upon the drum. i

In its normal position, the brake handle paWl, on account of the Weightof the handle thereof, WillY be in constant engagement with -the ratchetduring the winding up of the brake drum,Vv and in such Winding upon thereturn of the handle to its normal indrum, a pawl associated with saidoperative positionV the hanger rides in returnin movement upon theratchet. VTo release t e'drum, the holding pawl maybe dis engaged fromthe ratchet by.. means @of the handle 35 of said pawl. p

I claim:

1. Ina brake, a drum, a ratchet associated therewith, an operatinghandle, a pawl associated with said handle to engage the ratchet, and ahanger riding upon said ratchet and connected to the handle. y

2. In a brake, an axle, a drum mounted upon said axle, a ratchet,aassociated with said drum, a handle for operating said andle andadapted to engage the ratchet, and a hanger for supporting said handle,the said hanger riding .upon the ratchet. e

3. In a brake, an axle, a drum mounted thereon, aratchet connected tosaid drum, a handle, a pawl associated with said yhandle to engage the'vratchet, and a hanger pivotn ratchet, a pawl to engage the teeth of saidconnected to said handle, the said ratchet, and a hanger connected tosaid handle, the sald hanger riding upon the teeth of the ratchet. n y

5. InV a b rake, incombination, a drum, a brake cha-1n, and an axlepassing through the drum,y the'said drum being provided Y With anopening for the lpassage of a link of the chain, the said drumhavingshoulders over which the said link may be passed through saidopening, the axle passing near said link to prevent itsremoval from.said shoulders when the axle is in position.

v6. vIn a Winding mechanism, the combination with a casing, of a memberrotatably mounted within said casing, saidV member having a ratchetwheel rotatable in unison therewith,an arcuate hanger loosely mounted onsaid ratchet wheel and free to oscillat with respect to the latter, anoperating levei' pivotally attached tosaid hanger,said leverl having apaWl adapted to coperate with f said ratchet wheel. .f y l In Witnessthat claim the foregoing Iy have hereunto subscribed my name this 25thday of October 1916.
